The Future of Clean Diesel Is &#8230; Gasoline?

Although combinations of in-cylinder systems and exhaust after-treatment are the most likely ways manufacturers will meet clean-diesel requirements over the next five years, researchers are looking at alternative fuels, including gasoline. This alt-fuel interest is being pushed by the industry’s hope of finding a cleaner and more cost-effective way to power construction machinery.

Electrification already has made its debut in commercially available construction equipment during the past two years. For example, Komatsu has been producing its 22-ton PC200LC-8 hybrid excavator in Asia since 2008, and Caterpillar has been delivering D7E diesel-electric bulldozers since late last year.
